Jackson died from an apparent cardiac arrest on 25 June. Though his body was released the next day to relatives, his brain was not. The pop star's inert brain must "harden" for at least two weeks before doctors can conduct their neuropathology tests.
Doctors will examine Jackson's brain to help determine the cause of death, suspected of being linked to painkillers. Such examinations can also reveal unknown diseases, evidence of alcohol abuse or whether Jackson has suffered overdoses in the past.
Removing the brain is the "only way to carry out the tests" according to a source for the Mirror. "The tissue has to be examined. I can't tell you how long that is going to take."
